Beneficial Spell Effects that will affect Dynamic Range / Remove XP Buff

[Softcore PK]

I'm a little concerned about the teleport spells, in this situation. Druids and wizards often port for money, but if porting a level 50 brings you in range to them, then once they zone the higher character can kill the druid/wizard. And take their money (maybe more than what they paid) and cause exp loss.

EDIT: or does zoning remove the flag?
